Raleigh Bicycle

I am so disappointed. Bought a Raleigh bike with training wheels for my son. He loves it rides daily. The training wheels rubber though cam off within a week. I took the bike back to Makro Milnerton, where the Raleigh sales rep blamed me for the rubber coming off. He refused to replace it. The manager though was very helpful and replaced the wheels. The sales rep then said that he guaranteed that now because the wheels were balanced the rubber would not come off again. He 2 weeks later - rubber of training wheels is coming off again. So unfortunate - have tried to contact Raleigh themselves with no response from them. And all I get from the rep is that they will not replace them again. We bought the bike on 24 September - it's just over a month old and the training wheels rubber is not holding. Super disappointed.
